. 'To all whom it mayc'oncern: I

Be'it known that we, WALTER O. HOLT and RALPH -.L'EE'TE Fos'rnmpcitizens of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Lamp Shades, of which the following is a specification, reference being had therein lamp shade, and constitutes the blank therefor. Fig.

2 is'a' plan of four of said sections united in series on their contiguous edges, before bending. Fig. 3 is a per spective view of said four sections, bent to form the 'foursidedbody of a lamp'shade, but with the top pieces extending outwardly.- Fig.4 is a perspective view of the lamp shade after the top pieces have been bent down. Fig. 5 is a perspective view of the metallic top piece. Fig. 6 is a perspective view of the completed lamp shade. Fig. 7 is an inverted plan view of the completed lamp shade and illustrates the interior thereof. Fig. 8 is a perspective view showing the lamp shade as used in connection with an electric drop-light. Fig. 9 is a-view in front elevation showing the manner of mounting and fastening the lamp shade upon the hol der of an electric incandescent drop-light. Fig. 10 is a plan of a bottom piece which may be used with said lamp shade. Fig. 11 is a perspective view of said bottom piece with its flanges upturned. Fig. 12 is a perspective view of our improved lamp shade with said bottom piece attached in position. Fig. 13 is an enlarged detail view showing in perspective the manner of fastening said bottom piece to the lamp shade. I

Our invention relates to lamp shades for electric, gas, or other lights, and consists of tllo novel construction and combination of the several parts as hereinafter described and specifically set forth in the claims.

The body of the lamp shade is made of any suitable material, preferably pasteboard, or paper of sufficient stiffness to hold its shape. One ofthe sections is separately shown in Fig. 1, consisting of a truncated triangular piece 1, having at its base a flange 2, whose outer corners are in a beveled or acute-angled form; and also having a flange 3, whose outer corners are in the form of an obtuse angle. The piece 1 is provided 'with an ear or top 4, having a straight-bottom, right-angled side edges and a semi-circular top. A central aperture 5 is made as shown in Fig. 1. The left-hand edge of the body piece 1 is straight and has no-flange. The flange 2 is integral with the piece 1, but is bent along the line it; the flange 3 is integral with the piece 1, but is bent along the line y, and the top or car 4 is integral with the piece 1, but is bent along the line z. The piece 1 is preferably made of a pasteboard or paper,

sufficiently thick to be opaque or semi-opaque, and by cutting out portions thereof in a pattern (thus leaving openings or apertures 6) and-placing on the'back of the piece 1 a thin colored paper, which is translucent, indicated by '7 in Fig.7, a soft, tinted light shines through, reducing to an agreeable degree the intense glare of the electric or other light and adapting the shade to domestic use, or for decorative or advertising purposes.

Several of the pieces shown in Fig. l are united, as seen inFig. 2, by fastening them together by means of the flanges 3', pasted or otherwise secured, respec tively, to the adjacent straight edge of the contiguous piece, the flanges 2, overlapping loosely at their sides, and the ears 4 overlapping loosely at the adjacent sides, as illustrated in Fig. 2. Then the outermost flange 3, is bent over and upon the outermost straight edge and pasted or otherwise fastened there, whereupon the coinponnd pieces, shown in Fig. 2, assume the form seen in Fig. 3. Next, the ears or top pieces 4 are bent down successively, until they all lie flat and form a straight top of four thicknesses, as illustrated in Fig. 4, the holes or apertures 5 all registering with one another, as seen in Fig. 4. I

A metallic fastening piece 8 is shown in Fig. 5, consisting of a somewhat cup-shaped or flaring ring, and

several prongs 9 and flanges l0, all integral, preferably three of each. These flanges and prongs are inserted through all the holes 5 of the ear piece 4, and then the prongs 9 are bentover, as shown in Fig. 7, thus fastening all four of the ears 4 in position and holding them together firmly. The result is the completed lamp shade shown in Fig. 6. The body of the lamp shade is thus given the form of a truncated pyramid, and it possesses much rigidity, thereby being enabled to preserve its form in use. The metallic ring or fastening 5 and the folded ears 4, thereby secured together, give much strength and firmness to the structure, and the corner flaps or flanges 3 preserve the vertical edges or corners in shape.

'The flanges l0 protect the edges of the apertures 5 of the ears 4 from the heat of a gas light, or other flame; and, if the lamp shade is used in connection with an incandescent electric light, as shown in Fig. 8, the fastening piece 8 has another function. In Fig. 8 the electric'wire is indicated as 11, entering the usual holder 12, the latter being provided with the ears 13,

through which, respectively, pass the set screws 14. i The glass bulb of the electric light is seen at 15 in Fig. 9. In Fig. 9 one of the prongs 10 is represented as bent up against the under side of the ear 4 of the body of the lamp shade, and the flange 9 as passing through the apertures 5 of the ears 4. The outer edge of the ring or fastening device 8 passes up within the flange and ears of the holder 12. By turning the set screws 14, the

ner and is provided with a suitable fastening device,

that shown in the drawings consisting of a flexible metallic strip 20, bent at one end and passing through a cut 21 in the flange 18. A sheet of translucent colored paper 22 is pasted on the interior surface of the bottom piece 16, as shown in Fig. 11."

As seen in Figs. 12 and 13, the flanges18 of the bottom piece 16 are bent up over the outer surface of the flanges 2 of the lamp shade 1 and are held in that position by bending the inneren'd of the metallic fastening strip 20 at 23 (Fig. 11), and the middle thereof at 24 to secure by LettersP-atent:

1. 'ihe blank for the improved lamp shade herein de V scribed, consisting of the piece 1 in the shape -'ot a truncated triangle with a straight base 'w and a straight top 5 and provided with a side flange 3: and an ear piece 4 extending at a right angle with the top 2 and mnde with a central circular aperture I), all said pieces beingintegral.

:5. The blank for the improved lamp shade herein described. consisting of the piece 1 in the shape of a truncated triangle with a straight base a and a straight top 2 and provided with a bottom flange 2 and a side flange 3; and an ear piece 4 extending at a right angle with the top .2 and made with a central circular aperture 5, all said pieces being integral.

It. In a lamp shade. the combination of a plurality of side pieces 1; each having the shape of a truncated tritflioi'tom piece in said position upon the flanges of the body angle'nndprovided with a flange 3 and an ear 4 which has a circular opening said pieces being united by means of the flanges 2i overlapping and fastened to the adjacent edge of the contiguous piece 1. and having all the ears 4 heni down to lie in one plane with the openings 5 thereof registering each with the others.

4. The improved lamp shade herein-described.,consistlng of a plurality of pieces assembled in the term of a truncated pyramid. and consisting ol' a plurality of side pieces. each having the shape oi u truncated triangle and provided with a flange and an ear which has a circular aperture, said pieces being united by means of the flanges overlapping and fastenedto the adjacent edge of-the contiguous piece and having' all the ears bent down to lie in one plane with the apertures thereof registering each with the others. and a metallic ring or fastener adaptedto pass through all said registering apertures and having prongs which are capable of bending into contact with the lowermost of said ears for the purpose of confining them all in their tolded or closed position.

5. in a lamp shade, the combination of a tour-sided body portion in the shape of a truncated pyramid. having on -the base thereof outwardly a series otfour flaring flanges separated from each other by an intervening space; a

f rectaniguinr bottom piece having on the edges four folded iianges separated at their ends respectively and adapted to overlap the exterior surface of the flrstnnmed flanges,

sp'cctiveiy; and means for securing the flanges of the portion scriatim.

1i..in a lamp shade, the combination of a body portion in the shape of a truncated pyramid having on each edge of the base thereof an outwardly flaring flange: a bottom piece having on each edge a foldable flange adapted to ovcr lap the exterior surface of the flanges of the body portion and a flexible metallic strip secured at one end to each of the flanges of the bottom piece and adapted to form a hook at its opposite end to extend over the adjacent end of the contiguous flange of the bottom piece and also to underlie said bottom piece, thereby securing the bottom piece and body portion together along the whole contiguous surfaces of all said flanges.

in testimony whereof we afllx our signatures in presence of two witnesses.
